.SPECIFICATION forming part of Letters Patent No. 265,605, dated October 10, 1882.

Application llcd January 11, 1882. (Model.) I 1 To all whom it may concern Be it known'that I, JOSEPH R. HOOD, of Philadelphia, in the county of Philadelphia and State ot' Pennsylvania, ha-ve invented certain new and useful Improvements in Hoes, Rakes, &c.; and Ido hereby declare the following to be a full, clear, and exact description ot' the invention, such as will enable others skilled in the lart to which it pertains to make and use the same. y

My invention relates to an improvement in hoes, rakes, and other agricultural implements.

Heretofore hoe-blades have been adjustably secured to the hoe-handle by means of a round hook-bolt, the curved outer end ot which passes through around openingiu the hoe-blade, while the upper end passes through an opening in the eye or socket ofthe handle and is secured by means of a tlat thumb-nut, which rests on a flat boss formed on the eye or socket ot' the handle. This form of construction is objectionable, for the reason that the faces of the lat nut and dat boss will not correspond if the inclination or angle of thehOe-blade is changed, as the bolt by its different inclinations assumes a more or less transverse relation to the han dle, and thus causes the nut to bear or rest on one edge, and when sufficiently strained to secure the hoe-blade in position will bend or break the bolt. Another-objection to the use of this style of hoes now used is that the opening through the eye ot' the handle for the passage of the hook-bolt is just of size sutcient to allow the said bolt to pass through without allowing it any movement backward or forward, and consequently rendering the adjustable inclination ot' the hoe-blade impossible. Another objection to the above form of construction is that where no provision is made for the backand-forth movementot the hook-bolt only those hoe-blades having the openinginto which the curved end ofthe hook-bolt rests the same predetermined distance from the upper edge of the blade can be secured to the handle. An

objection to the use of the round bolt heretofore referred to is that in every attempt to fasten the hoe-blade to the handle the bolt turns with the nut, and when the implement is in use the bolt is caused by the jarring` to assume its original and proper position, and

l consequently leave the hoc-blade loosely secured in the handle.

The object of my invention is to obviate the defects above noted by providing means for securely fastening the blades to the handle in any desired inclination or angular adjustment.

With these ends in viewmy invention consists in certain details in construction and combinations ot' parts, as will be more fully described, and pointed out in the claims.

'In the accompanying drawings, Figure l is a view in side elevation of a hoe constructed according to my invention. Fig. 2 is a similar view, showing the manner of securing a wedge in position. Fig. 3 is a longitudinal sectional view. Fig. '4. is a detached view of the hook-bolt, and Fig.5 is a detached view of the wedge.

A represents a handle, to the outer end of which is secured the eye or socket B. This eye B, which receives the end of the belve or handle A, consists of a tubular or socketed plate, provided centrally with the oblong opening U for the passage of the hook-bolt D, and adapted to allow it to be moved forward and backward, according to the desired adjustment ot' the blade, and on its top or upper surface with the concave boss, on which the convex face a of the thumb-nut F rests. The handle A passes entirely through the eye or socket B, and is also provided with an'oblongor rectangular slot passing` transversely through the same and adapted to register with the openings in the eye B for the passage ot' the hookbolt D. The front or outer end ot' the eye or socket B and the handle A are so inclined that when the hoe-blade rests rmly against the same without the interposition of any wedge it stands at its most acute angle, and by interposing wedges of different thicknesses this angle can be increased until the blade stands at a right angle from the handle. The upper edge of this eye or socket B is widened or laterally extended and provided with a depending ange, G, arranged transversely to the length of the handle. vBy'providing this depending ange G agroove, H, is formed, into which is received the upper straight edge j' ot' thehoe-bladeI. ThiseyeorsocketBisalsoprovided with the side anges, g, and on its lower IOO edge or side with the depending lip or tla'nge h, which is merely a continuation otl the side flanges, g and g. The opening in the lower face ot' the eye or socket B passes centrally through this depending lip or tiange h, so as to allow the hook-bolt to fit snugly therein, and also to allow the point of bearingot' the bla-de I on the said book-bolt to be above the lower edge of the lip or tlange It, so that when the blade is secured in place by tightening the thumbnut the said lower edge ot' the depending lip or flange will not form a fulcrum against which the blade bears, and consequently will not strain the blade or cause it to bend while it is being secured in position. The depending tlange 7L extends down considerably below the eye or socket, and is strengthened by the ribs t, which latter are situated resl'iectively on opposite sides of the rectangular slot O, and form a continuation ofthe walls or lining ofthe said slot, which thoroughly houses and protects the hooked portion or end ot' -the bolt Dand prevents foreign matter from becoming clogged between the parts. The construction of the anges above described furnishes increased bearing-surfaces for the blade, and also for the wedge when it is necessary to use the same. rlhe depending lower flange also prevents the hook-bolt from turning while the blade is being secured in position.

D is the hook-bolt, having its upper end or shank portion screw-threaded for the attachment ofthe thumb-nut F, tbelatter having, as before stated, a convex under surface, a, that tits the concave boss E on the eye or socket B, thereby allowing the lower end ot' the bookbolt to be moved forward or backward, according to the' desired adjustment ot' the blade, and under all such varied adjustments insure a firm and equal bearing ot' the nut on the boss without undulystraining any parts. rlhe body portion c ot' this bolt is also formed rectangular in shape, which prevents itt'rom turning in the slot C, and is provided at its lower end with the curved hooked end J, adapted to project forward and enter the slot K in the blade I, the upper face ot' the said curved end being provided with rounded notch d, for the reception of' the bearing portion ot' the blade, and a second notch, d', back ofthe tirst one, in which rests or bears the slotted end of the wedge L. The peculiar curvature and construction of the lower end ot' this hook-bolt D allows it, when a short-headed blade is used, to lie up closely to the blade and to the eye or socket B, and thereby close the space where clogging matter would be likely to fasten itseltl when the boe or implement is being` used in wet earth or mortar. rlhis construction ot' parts also allows different sized plates, blades, rake, Ste., to be secured thereto with equal facility and tirmness. The upper surface ot' the eye or socket D is provided with the longitudinal rib e, adapted to increase its strength, while the lower end ofthe hook-bolt D is provided with the web or ribf, adapted to increase the thickness of the bolt atthe point where an increased amount of metal is most. needed. rlhe curved end oii'tbel1ook-bolt I) adapted to enter the oblong slot K ot the blade l and practically fill the same and prevent it from being tilled up with foreign matter.

M is a circular re-ent'orcing disk, secured to one side ot' the blade by rivets passing through the disk and blade. The oblong slot K, bct'ore referred to, is formed in the center ot' this` disk, and the strength of' the hoe is increased at this point, which prevents the edge ot' the hoe forming the top ot' the rectangular slot from being distorted in shape after constant and severe usage. Besides performing tbe function ot' relent'orcing the blade I, this disk M gives a second incline or adjustment to the blade when the latter is reversed, so that the disk comes between the blade and the hookbolt without the interposition ot' a wedge. When the blade is in the position shown in the drawings the re-enforcing disk M is located on the outerl side ot' the blade and a wedge is inserted between the blade and holding-shan k to move the lower portion of the blade outward. By reversing the blade the wedge is inserted between the reenforcing disk M and the holding-shank, thus enabling the blade to be moved forward a greater distance and more nearly to a vertical position.

Vben it is desired to increase the angle ot' the hoe-blade a wedge, L, ot' any suitable thickness and similar to those shown in the. drawings, is placed on the hook-bolt between the end ot' the eye or shank and the blade and the parts are tightened in the ordinary Inanner. These wedges L are all provided at their lower ends with oblong slots N, into which the curved end 4ot" the hook-bolt D passes, and which holds it against displacement.

Irlaving described the dit't'erent parts ot' my improvement, I will now brietly describe its mode ot' operation.

To secure the blade to the handle atits most acute angle, the thu1nb-nut F is loosened until the curved end ot' the hook-bolt can pass into the oblong slot K. The straight edge b of the hoe-blade I is then placed in the groove and the nut F tightened, which holds the blade tirmly against displacement. Then it is desired to increase the angle or inclination ot' vthe blade a wedge, L, is lirst placed on tbc hook-bolt l.) and moved backward until it rests in the rear notch, d', and then the blade is put on, as before described, and secured in the same manner. rlhe blade, when thus secured, is not only braced against longitudinal displacement, but also against any lateral or transverse displacement, as the hook-bolttits snugly within the oblongI opening in the blade, and thus serves to prevent the blade from twisting out ot' place.

It is evidentthat slight changes in the construction ofthe dit'erent parts of myimprovement might be resorted to without departing from the spirit ot' my invention, and hence I would have it understood that l do not limit myself to thecxact construction of parts shown IOO IIO

and described, but consider myself' at liberty to make such changes as come withinthe spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
